Tool Steel - Technical Data

What is the difference between conventional steelmaking, sprayform steelmaking and powder metallurgy steelmaking?   

Thinking of them as good, better, best helps to get a solid understanding.  

Each individual element in a tool steel imparts certain and specific  properties to the steel according to the percentage.  The effects of a single alloying element can be modified by the presence of other elements.  Below is a chart showing the alloying elements in Cold Work Tool Steels.  Read on to learn the effects of each alloying element.
